- To all whom it may concern:

Be it known that I, JANEH. MCCAIN, a

citizen of the United States, and a resident of Boy, in. the county of Fergus and State of Montana, have invented a certain new and useful Improvement in Dish-Washing Machines, of which the following is a specification.

The present invention relates to dish- Washin machines.

An 0 ject'of the present invention is to provide a machine or device of this character wherein the washing is efiected by water which is introduced into the body of the machine under pressure, the machine being provided with a suitable drain for carrying off the water after use.

Another object of the resent invention 1s to provide a machine of:.-t is character which will accommodate a relatively large number of dishes and the like to be cleaned, and which is provided with novel means for supporting the dishes in such posltion that all of the dishes will receive the sprayed water thereagainst and be thoroughly cleansed on both sides.

The invention further aims at the provision of improved means for distributing or spraying the water upon the dishes, and for supporting the dishes and thelr racks 1n an improved manner about the spray ng device.

The above, and other objects and advantages of this invention will be brought more clearly in the following detailed description of the resent preferred embodiment, the same being illustrated in the accompanying drawings wherein:

Figure 1 is a perspective view of a washing machine constructed accordin to the present invention, the same being s own as arranged in proximity to a sink and a dram board.

Fig. 2 is a vertical central section taken through the washing machine, parts of the sink and the drain board being shown in section.

Fig. 3 is a transverse section taken on the line 3-3 of Fig. 2,-showing the bottom of the washing machine.

Fig. 4 is a to plan view, enlarged, of one of the open rac s detachably mounted in the bottom of the washing machine and adapted to support silverware, irregular dishes and the like.

Fig. 5 is a detail perspective view of the same.

Fig. 6 is a side elevation of the same. Fig. 7 is a transverse section taken centrally through the rack, showing a slightly modified form of the same for supporting vegetable and other relatively large dishes in proper position in the body.

Fig. 8 is a top plan view of another form of the rack, showmg the means for supporting plates and saucers on edge and m a predetermined position in the body.

Fig. 9 is a transverse section taken vertically through the form shown in Fig. 8.

Fig. 10 is a top plan view of the spray tube. 7

Fig. 11 is a fragmentary section of the upper end of the same.

Referring to these drawings, wherein like parts are designated by similar characters of reference throughout the several views,

10 designates a sink of usual construction, and which in the present instance is disclosed as being formed of an integral casting. At one end ofthe sink 10, and formed integrally therewith is a vertically disposed hollow body or casing 11 which comprises the body of the was ing machine of this invention. This casing. 11 tapers downwardly, and has its upper end flush with the upper edge of the sink 10 and rovided with a top 12 which is substantia 1y flush with a drain board 13 arran ed at one side of the body 11 remotefrom t e sink 10. A supporting rib or flange 14 is formed across said remote side of the casing 11 in position to hold the drain board 13 flush with the top 12. A wall board 15, or flange, rises from the casing and extends entirely along the rear edges of the sink 10, the casing or body 11, and the drain board 13. The body 11 is open at its upper end, and provided with a marginal ledge or shoulder at the opening upon which is seated a cover or closure cap 16, the latter lyinlg flush with the up er face of the top 12. referably, the b0 y 11 is supported upon a stand or pedestal 17 which may be in the form of an integral casting adapted to rest upon the floor, and being of sufilcient height to engage against the lower end of the casing or body 11 to support it.

The body 11 1s provided centrally, with a vertically extendin spray tube and supporting post 18. As s own in Figs. 9 and 10 the post 18 is provided with a plurality oi relatively small openings or perforations through its lateral wall, as indlcated at 19, and is provided with a closed upper end or top 20 through which extend open in s or perforations 21, the latter being 1nc lned outwardly, or flaring upwardly to provlde a spreading stream or spray of water when the latter is admitted under pressure into the spray tube 18.

The bottom 22 of the body 11 1s rovided with a. threaded opening exten mg therethrough and having bosses about the opposite ends of the opening, as indicated at 23, and the lower open end of the post or spray tube 18 is externally threaded and adapted to be detachably secured into said 0 ening. A supply ipe 24 is threaded into t e lower end of t e opening 23 and is adapted to deliver hot water under pressure to the post or tube 18. Th1s supply ipe 24 leads from any suitable source of liot-water supply under pressure, and the water is adapted to be controlled in any usual manner, such as by means of a valve 25. located preferably upon the wall flange or board 15, immediately over the body 11. The bottom 22 of the body 11 is also rovided with a drain opening 26 covere by a strainer or screen disk 27, and to which is connected a drain pi e 28. I

The body 11 is provi ed, on Its inner wall, with annular ledges or shoulders 29 arranged in vertically-spaced apart relation, and adapted to sup ort a plurality of racks or open baskets wit in which are placed the dishes, and other articles adapted to be cleansed.

As shown in Figs. 4 to 9 inclusive, each of the dish racks is provided with a bottom formed of a plurality of concentrically arranged rings 30 which are interbraced and held together in a common plane by means of a plurality of wire strands 31 which extend substantially radially, and are threaded over and under the concenrrically arranged rings- 30, and which are rolled over or looped about certain of the rings as shown for interlockingthe structure and making the same rigld.

The central portion of each dish receptaeleis provided with a socket in the form of a pair of oppositely bowed or archedsupporting members 32 formed Ipreferably by a pair of substantially paral el strands of wire which extend diametrically across the 'bottom. The outwardly bowed supporting elements 32 provide at their opposite ends recesses or notches which form, together with the intermediate socket portion, an elongated opening extending substantially diametrically across the intermediate portion of the bottom of the receptacle. This socket, which may be designated as 32, is of a size ada ted to freely receive the post 18 upward y therethrough. The post 18 is provided at its with pairsof outwardly exte ng lugs or shoulders 33 which register with the anas soon as the receptacle has op site sides all" means? permit the passage of the lower receptacles or racks downwardly into the bottom of the body 11. As the body 11 flares upwardly, the receptacles, designated as 34, 35 and 36, correspond in diameter to the different positions which they assume in the body. The lowermost receptacle 36 is adapted to pass the upper pairs of lugs 33 and to be seated upon the lower annular shoulder 29 and the lowest pair of lugs 33. The lugs 33 extend from the diametrically'opposite sides of the 0st 18, and een placed upon its shoulder 29, the receptacle is given substantially a quarter 'turn to bring the recesses out of registry with the lugs 33. The lugs 33 therefore rest u on the outwardly bowed portions 32 o the socket. By means of this construction the racks or receptacles are capable of supporting considerable weight, and do not sag at their intermediate portions.

Each of the receptacles 34, 35 and 36 is provided with a marginal up-standing flange formed by extending the outer extremities of the radially extending strands 31, upwardly, and securing their upper ends to an upper ring- 37.

he upper receptacle 34 is divided into four parts, each part being provided with a plurality of closely-spaced-a art bars 38 which are secured at one en to the top ring 37, and which extend inwardly and have their opposite ends secured to-strands 39. The end bars 40 of each grou are spaced apart from and lie substantia lly in parallelism to the adjacent strands 39. The alternate bars 40 and strands 39 are rolled over I about a top ring 41 which connects the groups of bars 38 and support the same. The opposite alternate strands 39 and bars 40 are rolled over the top ring'41, andere extended downwardly and have engage ment with the inner rings 30 of the bottom structure. This construction permits the free passage of the receptacle downwardly over the post 18, and permits the turning of the receptacle on the post to dis ose the socket members 32 on the lugs or shoulders 33. Preferably, this receptacle 34 is placed at the upper enlarged end of the receptacle, and the receptacle is spaced downwardly from the top of the body 11 a sufiicient distance to permit the positioning of relatively large pla'tes edgewise between the bars 38. The intermediate receptacle or rack 35 is shown in Fi 7, and wherein the same is provided wit an inner wall arranged con-. centric to the outer rim, and comprising an inner ring 42 which is supported upon upwardly extending links 43 which are secured '43. The outer rimjor wall of each rec'epe f at their lower ends to one of theinterme-- diate' rings 30 at the bottom. The links 48 and the inner rings 42 are sup orted in raised position, and 'interbraced, y means of a second'inner ring 44 about which-is looped the intermediate portion of each liiik tacle, and the inner wall of the receptac '35 ma be provided with any number of rin or reinforcing and bracing the same an for providingbpenings of the desired size through the receptacle.

- The lowest receptacle 36 is in the form of a basket havin ginal rim or wall adapted to confine irregularly shaped articles therein, and which cannot be accommodated in the upper receptacles 34'and 35. e

In use, the cover 16 is removed from the receptacle 11, and the racks are raised one at a time through the open top of the receptacle or body. To remove the racks, it is only necessary to lift the top rack upwardly from the post 18. The lower racks, however, must be turned through substantionally a quarter of a turn to register the elon ated sockets with the laterally extending ugs 33 on the post. When adjusted into this position, the lower racks may readily be raised. The racks may be spread out upon the drain board 13, and the dishes or the like placed therein. The racks are now fitted into the body 11 about the post 18, and the cover 16 is replaced to seal the top of the receptacle. The valve 25 is now manipulated to turn on hot water under pressure into the bottom of the spray tube 18. The water passing into the tube 18 is projected into relatively fine streams through the lateral openings 19, and is delivered upwardly into a diverging or spreading stream of water from the top of the spray tube against the cover 16, the water being deflected thereby downwardly into the body 11 and between the dishes which are placed, particularly on the upper rack 34.

The water dripping from the dishes on the racks, and from the sides of the body 11, is collected on the bottom 22 and passes outwardly through the drain opening 26 and drain pipe 28. The cover 16 is now removed, and the steam is permitted to escape.

Dishes are left in this position for several minutes, and the heat absorbed thereb is suflicient to dry the same in a relatively s ort time. The racks or receptacles may now be removed from the body 11, and the dishes may be stored in any desired manner for future use;

It will be particularly noted, from the position shown in Fig. 1 of the accompanying drawings, that the novel formation of the receptacle or body 11 at one side of the sink 10, and interposed between the sink and the bottom structure above described, an provided with the marsurface of the the drain-board 11 provides notonly a neat and attractive structure, but one which is compact and readily accessible, and wherein the dish receptacle 11 is so positionedfthat the dishes may be quickly removedv or positioned with respect to the washing machine, and any dripping from the dishes, silver ware or the like in either positioningor removing the same from the washing machine, may be caught on the drain board13 and in the sink 10. The arran ement is also believed to be sanitary, as t e drain board and the top of the receptacle may be kept clean by merely wiping the same and permitti the water to drain down into the sink 10.

The receptacle 11 may be cast integrally with the sink 10, or be made as a part there- 'of of sheet. metal, porcelain or the likesuch as is found convenient in manufacture, and which may be readily handled and installed.

It is of course understood that various changes andmodifications ma be made in the above-specifically describe construction of washing machines and parts ad'acent thereto, without delparting from the spirit of this invention, an the scope of the following claims.
